Cron every day at 9 a.m.

The cron expression for every day at 9 a.m. is 0 9 * * *. How to make it 9 a.m. in your time zone, not the server's, weekday variants, and GitHub Actions and AWS forms.

The expression

0 9 * * *

Runs once a day at 09:00, every day of the week, including weekends.

Field Value Meaning
Minute 0 at minute 0
Hour 9 at 9 a.m. (hours are 0-23)
Day of month * every day
Month * every month
Day of week * every day of the week

Cron uses a 24-hour clock with no a.m./p.m., so 9 a.m. is 9 and 9 p.m. is 21. The question that matters is whose 9 a.m.: cron uses the time zone of the machine or scheduler running it.

Variants

Schedule Expression
Every day at 9:30 30 9 * * *
Every day at 9 p.m. 0 21 * * *
Weekdays at 9:00 0 9 * * 1-5
9:00 and 21:00 0 9,21 * * *
Every hour from 9 to 17 on weekdays 0 9-17 * * 1-5
Every day at midnight 0 0 * * *

Where to write it

  • crontab (Linux, macOS): 0 9 * * * /usr/local/bin/morning-report.sh in crontab -e. Check the server zone with timedatectl; on cronie you can put CRON_TZ=Europe/Paris at the top of the crontab to get 9 a.m. Paris time regardless.
  • GitHub Actions: schedules are always UTC, so convert. 9 a.m. in New York is 0 13 * * * during daylight saving time (EDT, UTC-4) and 0 14 * * * in winter (EST, UTC-5); 9 a.m. in London is 0 8 * * * in summer and 0 9 * * * in winter. Either update it twice a year or accept an hour of drift.
  • Kubernetes CronJob: schedule: "0 9 * * *" with timeZone: "America/New_York", which follows daylight saving automatically (stable since Kubernetes 1.27).
  • AWS EventBridge: rules use UTC: cron(0 9 * * ? *) is 09:00 UTC. EventBridge Scheduler accepts a time zone (ScheduleExpressionTimezone), which keeps 9 a.m. local through DST.

Common mistakes

  • * 9 * * * runs 60 times, every minute from 9:00 to 9:59.
  • 9 * * * * runs every hour, at nine minutes past.
  • 0 9 * * * includes weekends. Add 1-5 in the last field for Monday to Friday.
  • DST on UTC schedulers. A fixed UTC hour moves by an hour locally twice a year in zones with daylight saving.
